Patent GB-928283-A (GB)
Title: A refractory shape and composition
IPC: C04B38/08
Filed: 1961-04-21
Abstract: A green lightweight insulating refractory is formed of 15 to 25% of expanded perlite and the remainder heavy aggregate, at least 25% of the total solids being dead burned magnesite, all particles of which pass a 65 mesh Tyler screen.  On firing the magnesia reacts with the perlite to form forsterite and spinel. Part of the dead burn magnesite can be replaced by other materials for example olivine in amounts up to 40% by weight of the total aggregate, chrome ore in amounts up to 25% by weight, alumina up to 20% by weight or ternary mixtures containing up to 20% alumina, up to 30% olivine and the remainder dead burn magnesite may be used.  Clay may be added in amounts up to 5% by weight to improve workability.  The other heavy aggregates, other than magnesite should be at least as fine as 28 mesh whilst the alumina is preferably -325 mesh.  In manufacturing shapes such as brick, expanded perlite is mixed with water, with or without a binding agent such as waste sulfite liquor, epsom salts, nitre cake or magnesium chloride in amounts up to 5% of the total weight of the solids; about 5% water based on the total solids is used.  The aggregate components are then added and mixed and the charge after moulding is dried at about 230 DEG F. and fired at 2670 DEG F.  A large number of examples are given illustrating the properties obtained when magnesite and perlite mixtures in varying proportions are prepared and of mixtures containing magnesite and perlite together with olivine, chrome ore and ball clay, alumina, olivine and alumina, and ball clay.

Title: Blind rivet assembly
IPC: F16B19/10
Filed: 1976-04-12
Abstract: 1490508 Blind rivet assembly TEXTRON Inc 12 April 1976 [19 June 1975] 14796/76 Heading F2H [Also in Division B3] In a blind rivet assembly comprising a tubular sleeve 1 having a head 2 provided with a recess 27 at one end and an expandable tail at the other end, and a stem 4 provided with a pulling portion 6 at one end and a former 14 at its other end, said stem also having a plug portion 23, a locking groove 17, and a portion 8 having a diameter smaller than the internal diameter of the sleeve and head, a locking collar 21 is provided within the sleeve, said collar having a head 22 which fits in groove 17, the arrangement being such that when the stem is pulled to expand the tail and set the rivet, the collar moves with the stem through the sleeve until obstructed from further movement, the collar then being expanded into recess 27 to form an interlocking rib 29, see Fig. 3. The skirt of the collar overlaps break groove 24 sufficiently to ensure that the collar has been expanded into the recess to form the rib by the time shoulder 25 abuts the bottom surface 28 of tip 11 of the riveting tool, after which further pull on the stem causes fracture at the break groove. A washer 13, see Fig. 1, may be located between head 2 and the bottom surface of the tip of the riveting tool. In a modification (Fig. 5, not shown), stem portion 26 is of substantially the same diameter as stem portion 8 so that shoulder 25 is not large enough to abut against tip 11 or washer 13. In this case, compaction of the skirt of the collar into the recess provides sufficient stopping reistance to movement of the stem to cause fracture at the break groove when the shoulder is flush with the top surface of the head 2.

Title: Improvements in or relating to positional control means, particularly for use in thesteering of dirigible craft
IPC: F01D15/02
Filed: 1937-05-28
Abstract: 491,400. Electric remote control systems. SPERRY GYROSCOPE CO., Inc. May 28, 1937, No. 14901. Convention date, June 3, 1936. [Class 40 (i)] The steering-gear of a ship is operated by hydraulic power under control of an electric remote-control system, a return supervisory self-synchronous electrical signalling system being used to indicate rudder position and to operate the follow-up mechanism. When the steering wheel 1 is turned, one of the rollers 23 engages one of the conducting segments 5, 6 to complete a circuit to drive motor 35 clockwise or anticlockwise, the valve 43 being turned by the motor. Hydraulic power is thus supplied to servomotor 47 to move piston 55. The valve 63 is thus adjusted so that the hydraulic motor 54 is started up to move the rudder 3, the floating beam follow-up 56, 60 stopping the hydraulic motor when the required displacement has taken place. The piston 55 of the servomotor 47 is geared to the transmitter 18 of a polyphase, single phase signalling system, the receiver 15 of which moves pointer 40 to indicate the position of the rudder and also moves arm 22 to follow-up the movement of the steering wheel, the circuit to motor 35 being opened when the roller contacts 23 are moved off the conducting segments. If the wheel 1 is released, it is restored to its central position by spring 64, the ends of which act respectively on fixed and moving members associated with the ship and wheel respectively, and the mechanism operates to bring the rudder into its central position. A similar spring 74 is used to position the rotor 37 of motor 35 in a position at right-angles to the field-coils. If desired the motor 35, and so the rudder mechanism, can be controlled by push-buttons 81, 82 for sending the boat to port and starboard respectively, the push-buttons being inoperative unless relay 21 is released. The motor 35 is series wound, but another embodiment in which a shunt-wound motor is used, relays being provided to control the direction of rotation, is also described. Specifications 299,083, [Class 114], and 408,697 are referred to.

Abstract: 1,268,132. Textile finishing compositions. ROHM & HAAS CO. 26 March, 1970 [3 April, 1969], No. 14914/70. Heading D1P. Compositions for modifying fibrous materials comprise a non-aqueous dispersion of an acid polymer in a medium comprising perchloroethylene, trichloroethylene or 1,1,1-trichloroethane or a mixture of two or more of these. The acid polymer is derived from monoethylenically unsaturated molecules and contains 20-80% by weight of mers of at least one α, #-monoethylenically unsaturated carboxylic acid and 80-20% by weights of mers of at least one other α, #-monoethylenically unsaturated monomer having a CH 2 =C# group. The acid polymer is maintained in stable dispersion within the chlorinated hydrocarbon medium, in which it is insoluble, by means of a polymeric dispersing agent having one component which is solvated by the chlorinated hydrocarbon medium and another component which is associated with the dispersion polymer. The dispersion is obtained by the polymerisation of the unsaturated molecules in the medium in which there is dissolved 1- 20% by weight, based on the weight of the unsaturated molecules, of a polymer of at least one (C 8 -C 18 ) alkyl acrylate or (C 8 -C 18 ) alkyl methacrylate. On polymerisation the dispersion contains particles having sizes of 0.03- 10 microns. Materials treated are made of hydrophobic fibers such as linear polyesters, polyamides, polyurethanes and resin-treated cotton and wool. After applying the composition. which has a solids concentration from 5-50 % by weight, to the material is dried and optionally the polymer is cured to impart resistance to water and organic solvents. The non- aqueous dispersion may include, in addition to those to impart soil release, modifying agents to impart crease resistance, durable press characteristics and shrinkage control. A catalyst may be incorporated to help in curing and the curing conditions can be varied to provide either. temporary or permanent soil release.
